I put the following in my doc area, called it "phpinfo.php", and browsed
it.

<?php
phpinfo();
?>

On my machine I see I have environment variables called

SERVER_ADDR 127.0.0.1
SERVER_NAME perk.localdomain

I forget how to access the environment from php, but I'm sure it's easy,
and it might change on different php versions anyway. You should have
something similar, though it will also depend on the web server software.

_HOWEVER_, a web server machine does not have to have a name, so you can
not depend 100% on finding a name at all. You might need to settle for an
ip address.
